What time is it?
Summertime
It's our vacation
What time is it?
Party time
That's right, say it loud

What time is it?
The time of our lives
Anticipation
What time is it?
Summertime
School's out, scream and shout!

[Troy]
Finally summer's here
Good to be chiilin' out
I'm off the clock
The pressures out
Now my girl's what it's all about

[Gabriella]
Ready for some sunshine
For my heart to take a chance
I'm here to stay
Not movin' away
Ready for a summer romance

[Troy and Gabriella]
Everybody ready, going crazy, yeah we're out
Come on and let me hear you say it now, right now

What time is it?
Summertime
It's our vacation
What time is it?
Party time
That's right, say it loud

What time is it?
The time of our lives
Anticipation
What time is it?
Summertime
School's out, scream and shout!

[Sharpay]
We've got no rules
No summer school
I'm free to shop till I drop

[Ryan]
It's an education vacation

[Sharpay and Ryan]
And the party never has to stop

[Sharpay]
We've got things to do
I'll see you soon

[Ryan]
And we're really gonna miss you all

[Sharpay]
I'll see you and you

[Ryan]
And you and you

[Sharpay and Ryan]
Bye bye until next fall

[Sharpay]
Bye bye

[Sharpay and Ryan]
Everybody ready going crazy yeah we're out
Come on and let me here you say it now right now

What time is it?
Summertime
It's our vacation
What time is it?
Party time
That's right, say it loud

What time is it?
The time of our lives
Anticipation
What time is it?
Summertime
School's out, scream and shout!

[Troy and Gabriella]
No more wakin' up at 6 am
'Cause now our time is all our own

[Sharpay and Ryan]
Enough already, we're waiting come on let's go

[All]
Out of control

[Others]
All right
Everybody
Yeah
Come on

[All]
School pride lets show it
The champions we know it
Wildcats
Are the best
Red white and gold

When it's time to win we do it
We're number one we proved it
Let's live it up
Party down
That's what the summer's all about

[All]
What time is it?

[Gabriella]
Summertime is finally here

[All]
Let's celebrate

[Troy and Gabriella]
We wanna hear you loud and clear now

[All]
School's out

[Chad and Taylor]
We can sleep as late as we want to

[All]
It's party time

[Troy, Gabriella, Sharpay, Ryan, Chad, and Taylor]
Now we can do whatever we wanna do

[All]
What time is it
It's summertime
We're lovin' it
Come on and say okay now
what time is it
It's party time
Let's go and have
The time of our lives (more) (less)
